Thyroid iodine release measured by the double isotope method of Nicoloff was studied in patients with manic-depressive illness before, during and after treatment with lithium carbonate. The urinary lZSI/ZalI isotope ratio was measured following administration of Nal~SI and z3~I-thyroxine. In three o

Abstract
It has been established practice for 60 years to prepare thyrotoxic patients undergoing thyroidectomy with Lugol's iodine. However, evidence in support of its claimed benefits, namely a reduction in the vascularity and friability of the toxic thyroid gland, is scanty. We have therefore determined the effect of Lugol's iodine on thyroid blood flow, as measured by thyroid uptake of thallium-201, in nine patients with Gravesβ disease and one euthyroid patient. Thallium-201 uptake, as well as serum thyroxine and triiodothyronine, fell significantly after treatment with iodine. Although not correlated with thyroid function tests, thallium-201 uptake was significantly correlated with thyroid weight. These results support the contention that thyroid blood flow is reduced in thyrotoxic patients treated with Lugol's iodine.

## Abstract ## Background. The purpose of this study was to assess the late side effects of radioiodine therapy (RIT) on salivary gland function. One hundred eighty two patients were evaluated. ## Methods. Assessment of salivary gland function was performed with salivary gland scintigraphy (SGS)
Medical treatment of angina pectoris is largely based on the use of beta-blocking agents, calcium antagonists, and nitrates. Oxyfedrine, an amino ketone derivative and partial agonist at beta receptors, has been shown to have potent antianginal properties and to increase coronary blood flow in norma
